According to the second approach the expected loss for every one of the three basic groups of damages as mentioned above must be evaluated with the assumption that the individual losses in the frame of the damage group have the same value. For instance, the losses resulting from failures of electrical and electronic internal systems due to strikes in different parts of an establishment are the same, but they may be different from those for the damage group. The losses for the damage group may be greater, so special reduction factors must be selected in an arbitrary way. The damage group losses and reduction factors depend primarily on the type of structure and its features.
It should be noted that considerations involving the loss are intended to indicate the way in which they should be involved in the risk assessment. The values of loss may differ significantly depending on the local conditions, so the values given in this chapter should be treated as one of many possible examples.
